I have installed the Intense Debate comment system. It was supposed to keep the old Disqus comments but apparently did not. I am not a fan of Disqus so I hope readers will forgive me if their old comments are no longer visible.
Frequent commenters may wish to create their own profile with gravatar and links to your blog at Intense Debate so that information will be available to readers here.
You will also note the other new features like the thumbs up, or thumbs down voting. If you like a comment, click on the thumbs up and click thumbs down if you don't.
